The Channel Islands airspace is from 49 degrees north to 50 degrees north and allmost 2 degrees west to 3 degrees west in size upto 19500 feet.
The Zone on average has 400 to 500 movements in a sixteen hour period which equates to 25 to 30 movements an hour some hours are more and some are less.
These aircraft can range from a Cessna 152 to a Boeing 757 or Airbus 320 or similar types of aircraft so a wide variety of speeds have to be taken into this.
If it was not class A airspace maybe some one would make a suggestion on the type it should be???
